We bought a new set of CVR's at our club with the black mics. We had problems with the range of them. What I mean is the younger shooters were not setting off the machine. We upgraded to the white turbo mics from Bob Shultz and had no problems since. The original set of mics are in great shape and are for sale. $100.00 or best offer. If interested please email me at [email protected] I also want to double check that they are still there. Dave T.
